I think there are 3 posts in this thread about Covid being less deadly than “typical” winter season Influenza strains below a certain age, like 50 years old for males.

Influenza H1N1 in years 1917-1919 was more deadly in humans than Covid-19

Influenza H2N2 in years 1957-1958 was in the same human fatality range as Covid-19

Influenza H5N1 aka “bird flu”
has not caused a human epidemic yet,
but seems to kill more than 20% of the humans who have caught it.
H5N1 has killed billions of birds.

If you are a male over 50 years old,
have type A blood,
are overweight,
have a heart problem like right atrial enlargement,
have COPD,
have diabetes,
have kidney disease,
then Covid-19 infection is something to take extensive steps to avoid.
